Here's something to help tide you over until the season 5 premiere of Mad Men at the end of March. AMC has released a slew of shiny teaser trailers letting us know that Don, Roger, Peggy and friends are back in action and better that ever.

Unfortunately, all of the teasers are made up entirely of season 4 footage, but let's not pass up a chance to witness El Hammo in all of his slick-backed glory.
